Evidences:
1) The site is set to allow 500Mb uploads but suddenly you have one Forum that won't allow anything more than 100Mb as an upload.
2) Teachers get un-enrolled from their own courses and are suddenly students
3) Moodle assistant - administrators that could assist you for more than 2 years can suddenly not see an Administration Block.
4) 2900 people get un-enrolled from the entire site. It happened over the weekend and you are the only one who can remove them. Oh and Internet was down from home so you know it was not you.
